Weekend Link Love – Edition 188

By Mark Sisson

How one awesome kid gets to school every morning. I’d say that beats the pants off taking the bus, wouldn’t you?

From Dr. Briffa, the dark side of sunscreens: how sunblock doesn’t seem to do much against melanoma (and it may even make it worse).

The Complete Idiot’s Guide to Eating Paleo, a great introduction to the world of ancestral eating and health for the uninitiated, was recently released. Go check it out.

Breastfeeding babes begets beneficial gene expression in their immune system and helps bolster their intestinal stability. In other words, breast is by far best.

Cultured Caveman, Portland’s first 100% paleo food cart, recently surpassed their designated Kickstarter funding goal. Now, Not So Fast! is trying to do the same thing in San Diego with a Primal-friendly cart serving grass-fed and -finished meat, sweet potato poutine, Primal fish tacos, and local produce. They’ve got a few weeks to go, and they need your help.

City-living appears to cause more coronary calcification than country-living, and it might be the pollution.

Next time you’re about to pop a soy product into your mouth, think back to this article and see how you feel.

Mark Sisson got me pregnant.

– Whoa, whoa, hey there. What’s that? Oh, okay. Carry on then.

  1. Just donated to Not To Fast! since I’ll be moving down that way.

  2. I read the Dr. Briffa post and the year 2000 press release it linked to. The take-away from this is that, in some studies, people who use sunscreen are also more likely to develop melanoma. To me, this seems to be much more likely to be *correlative* than *causal*, since fair skinned people who sunburn easily are also most likely to develop melanoma. I would hate to see people make a decision not to use sunscreen based on solely on Dr. Britta’s post.

  3. Oh, and thanks for the shout-out to Portland! I can’t wait to try the Cultured Caveman cart.

  4. Dr. Briffa clearly states, and the study supports, that sunscreen does prevent sunburn and decreases the risk of skin cancer. The exception is when people use sunscreen to extend their time in the sun beyond what they would normally expose themselves to. This study doesn’t state that sunscreen itself is a carcinogen that increases your risk of skin cancer, rather it increases risky behavior that may lead to the development of skin cancer, especially in people who are fair-skinned.

    As a melanoma survivor (many, many sunburns in my lifetime), my first line of defense is protective clothing and a hat, second line of defense is staying in the shade, and my third line of defense is sunscreen. Melanoma is not always associated with sun exposure, but in my case it definitely was (plus a brief foray into the stupidity of tanning beds). Please don’t sensationalize this study and in a few words make it look like sunscreen causes skin cancer.

    Sunscreen is part of a comprehensive sun protection plan for those who have decided that sun exposure may not be a wise choice, particularly for people at high risk of skin cancer. Maybe getting more sun would help protect me, as many in the Paleo community believe, but it’s not a risk I’m willing to take. I’ll take my vitamin D and limit my unprotected sun exposure to 6 a.m. when the sun is just coming up and I’m giving thanks for being alive, well and Paleo.

    1. Read again carefully how Mark worded this:

      “how sunblock doesn’t seem to do much against melanoma (and it may even make it worse).”

      This is exactly what the article states–that it appears, according to studies, to do little to decrease the risk of contracting melanoma. It may make the risk worse because it provides people with a false sense of security. No where did Mark state that sunscreen itself leads to cancer. Considering that conventional wisdom has always supported the use of sunscreen to protect against “skin cancer” (blanket statement,) what Mark was stating is not only accurate and in accord with the article but also very important.

      And although neither Mark nor Dr Briffa alluded to this, I’m willing to be a little more “sensationalist,” as this is not my website, and hazard to guess that slathering a lot of evolutionarily novel chemicals on your skin may even contribute to the risk of melanoma.

      At any rate, glad you survived your experience with melanoma and that you’re taking measures to avoid it in the future 🙂

  5. Thanks, Mark, for the link the the Cultured Caveman! Can’t wait to try this out–I love the food cart culture here in the PNW but have mostly avoided them as they are mostly far from Primal/paleo. Exciting that we have that, and restaurants, such as Dick’s Kitchen, who seek to cater to the paleo crowd here!

  6. Portlandia rules. How I long for primal eating-out options up here in Seattle…tonight an car emergency forced us to stop for dinner, and we split a broiled hamburger (at a “casual dining” restaurant) ignoring the bun and nibbling a few french fries…I longed for better choices.

  7. Of course, now that we have a Complete Idiot’s guide, I expect we will be the next hot thing down the pike.

  8. Could somebody tell me how that kid gets too school? I can’t watch the video in my country

    1. he rode his bike – but wow! doing tricks and fancy moves…

    2. He rode a bike but propels himself with his legs as the bike is pedal-less. Plus he did a few tricks here and there!

  9. there is no question that breastfeeding is best for babies and mother.
    even on less-than-optimal diets, the factors in human milk and the way the mouth forms in breast-fed infants lead to better health and fewer braces!

  10. One thing that was not discussed in the sunscreen artile was the type of sunscreens used. In 2000 (when the study that this article was based on) many commercial sunscreens were not “full-spectrum”. They only blocked the burning UVB rays not the melanoma-causing UVA rays. This meant that using sunscreen to extend your non-burning time in the sun incresed your UVA exposure and your risk of developing melanomas.

    Once scientists became aware of the UVA/UVB relation to the various types of skin cancers, they becan pushing for full-spectrun sunscreens (beyond the zinc-oxide based ones that were always full-spectrum). Now I don’t know if anyone is making sunscreen that is not full-spectrum.

    I still am doing my best to naturally increase my sun tolerance and have always kept covered up (as I am very fair) but the author of this article did a disservice to his readers by not acknowledging the likely causes of this incresed cancer risk, and how sunscreens have changed in the past 12 years.

  11. Of course breast is best…when you’re successful at it. No on disputes that. Linking to articles proving it isn’t going to change anything, and just makes mothers who have struggled in their effort to provide the “best” for their babies feel like crap. The support systems for breastfeeding mothers are what is lacking, not information. Interestingly, the article you linked to also linked out to a study that showed formula fed infants who receive probiotics have similarly heightened immunity. Just an FYI so mother’s who visit your site and weren’t successful at breastfeeding don’t think their children are doomed. It’s supremely unhelpful to shout “breast is best” and not provide other information to mothers who weren’t successful.
